Perchlorate, the explosive main ingredient of rocket and missile fuel, can cause thyroid function problems at high levels in adults and low levels in children. It gets into the ground water and then food grown in there. Environmentalists argue that the level of perchlorate in water should be no more than .1 ppb (parts per billion), the EPA states that 15 ppb is a safe level, while the government is pushing for 200 ppb.
